Like New:
No scratches on the front screen, Free of any clearly visible dents. Works perfectly almost like a brand new phone.
Very Good:
Minor scratches may be on the screen or on the body of the phone but close to invisible difficult to be seen with naked eyes, Phones will work perfectly.
Good:
Visible scratches on the side of the device can also have thin lines on the screen or back of the body. However, these can be covered up by the case or tempered glass and there will be no problem with the performance of the device.
